After the first flights of the Odin, I'm finally back to discussing its assembly. Nothing particularly special about the assembly, but a few tips and precautions. I decided to mount the elevator servos at the front rather than in the rear boom. The fuselage cross-section doesn't allow for the installation of traditional 12m servos. I had to switch to MKS HV 6100 servos, which are smaller and, more importantly, shorter. They fit perfectly. I designed and 3D-printed a servo tray in carbon PETG. The elevator control linkages are already finished on the tail end; you just need to glue a threaded metal rod to its end to accept a clevis. I used MPJET plastic, which I've been using for years with complete satisfaction. In the wings, I installed the LDS servo room and used HBL 6625 servos for the flaps and HBL6625 mini servos for the ailerons. If there's room for the flaps, the wing's thinness means the 10mm servos just barely fit at the ailerons, and they need to be moved towards the spar to gain a little more clearance.
The green connector, once wired, is glued into the fuselage between two 1mm plywood plates that pass through, providing good support and adhesion. On the wing side, I left the connectors free for once because the wing root fairing is angled, and the wing root's translation prevents gluing this connector to the wing side.
Back to the fuselage. The battery is a 2S 3000mAh Li-Ion, and the receiver is a Jeti REX 7 Slim. The standard REX6 is too wide.
For the wing ballast (14mm x 14mm), I opted for a brass tube filled with lead. This gives me ten 100g ballasts. Next, I filled the ballast compartments of the wing joiner with 4/6 tungsten slugs and 2/6 brass slugs, all from my FS6 ballast set.
I already explained in a previous post how I made the centering lead. I needed 130g molded + 45g (3 x 15g) removable weights for a center of gravity at 100mm. Unfortunately, the center of gravity shifts quite quickly as soon as the ballast compartment in the wing is full. The forward CG thus shifts by about 6mm, which is significant. I therefore have to gradually remove the 45g of lead from the nose to maintain the recommended center of gravity around the ideal position.
I know the manufacturer is working on a suitable solution that should prevent this problem.
Finally, the glider weighs 2380g empty.
